EL34 MULLARD XF2, BROWN BASE, TWIN GETTER, MATCHED PAIR
EL34, MULLARD XF2, BROWN BASE, TWIN GETTER, MATCHED PAIR.
A very nice matched pair of these twin getter, brown base xF2 Mullard Valves. Both devices have beautiful low loss micanol "hole in spigot" bases, show minimal white "Old Shield" print along with twin getters ( one device twin halo, second device, twin D).
Both show emission profiles that match for both Ia and Gm.
